Title: Potentiometer
IPC: H01C10/40
Filed: 1969-01-30
Abstract: 1,216,634. Potentiometers. WELWYN ELECTRIC Ltd. 30 Jan., 1969 [5 Feb., 1968], No. 5189/69. Heading H1S. In a potentiometer having a movable contact 40 (Fig. 1) with arms 66, 62 (Fig. 11) engaging a resistance element 20 and a collector strip 34, respectively, the contact driving means 42 passes without direct contact through the contact carrying block 70, the driving means 42 and block 70 being linked by a spring member 82 having a portion 90 which engages the housing and resiliently holds the spring 82 in driving engagement with the driving means. The carrier block 70, whose tapered legs 74 (Fig. 10) straddle the driving means 42, is held against the top wall 14 of the housing by the resilience of the three-fingered arm 66 of the movable contact 40. The contact 40 is secured in a dove-tail groove in the block 70. The relative positions of the resistance element 20 and contact arm 66 are determined only by the sizes of four precisionmoulded pillars 96 and the carrier block 70. When the block 70 is moved to an extreme end of the housing, the ends 100 of the spring 82 press against the pillars 96 and cause the detents 86 (Fig. 11) to lift off the screw-thread, thus preventing damage and "backlash" between screw and contact movement. Printed circuit board terminals 30<SP>1</SP>, 32<SP>1</SP>, 38<SP>1</SP> may replace terminals 30, 32, 38. The collector strip 34 may be made of gold inlay over a brass base, and the contact 40 of precious metals.

Patent GB-628406-A (GB)
Title: Improvements in and relating to amplitude monitors
IPC: G01R29/06
Filed: 1947-02-25
Abstract: 628,406. Monitoring amplitude of electric oscillations. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. Feb. 25, 1947, No. 5480. [Class 40 (v)] In an amplitude monitor, voltage pulses are produced in response to parts of oscillations exceeding a certain amplitude and relays are adapted to actuate indicating devices in response to the voltage pulses. The signal to be monitored is applied to a jack 16, Fig. 2, amplified by means of valves 17 and 18 and developed across the primary winding 23 of a transformer 22. In the circuit of the secondary winding 21 are two diodes 24, 25, biassed to be normally non-conductive so that if the peak level of the oscillation appearing across the half of the secondary winding exceeds this bias a negative pulse is produced across a load resistor 33. This pulse is applied by means of contacts A1 of a normally operated relay A, to an electronic relay consisting of valves 37, 38 and 39 as described in Specification 628,409. When the anode current of valve 37 falls below a critical value, due to the effect of the applied pulse, the relay A in the anode circuit is released and the contacts A1 assume the position shown, disconnecting valve 37 from further impulses. When the contacts of relay A are released as shown in Fig. 3, a condenser 53 is charged through a resistance 54 from a current source from terminals 55, 56. The electronic relay is designed to return to its normal condition after three seconds so that the relay A then assumes its operated condition and a second relay B is then energized by means of condenser 53. If no further pulses arrive on the suppressor grid of valve 37 the relay B becomes de-energized after one second. If, however, a second pulse arrives during this second the relay B remains operated, being energized via contacts B1 and A3 until the relay A once more assumes an operated condition. The relays are supported so that when relay A is first released an indicating device is operated, and if the relay A is released a second time during the period of energization of the relay B a second indicating device is operated in addition (Fig. 4, not shown).

Filed: 1948-02-26
Abstract: 641,304. Rotary compressors. MARBLE, J. C. Feb. 26, 1948, No. 5756. Convention date, Aug. 21, 1943. [Class 110(ii)] In a meshing screw compressor valve means 38, 40 are provided to limit the pressure differential between the delivery end of the rotor chamber and the receiving chamber 16. When the pressure in the latter is reduced, e.g. when supplying air to an aircraft engine at high altitude, the valves lift against their light springs 42, 44 so that the compressor delivers air at a lower pressure. The compressor comprises a casing 10 containing male and female rotors 18, 20, an end wall 14 for closing the working spaces of the compressor. the wall being cut away to provide an outlet port a ... h. The inlet port may be combined radialaxial, or entirely axial, of known design. The valves may be placed in various positions. Fig. 3 shows a compressor with an inlet 70 and delivery 56, and control valves 50, 60, 62, placed as shown and communicating with the delivery. Before a groove 24 has passed out of registry with the valve 50 it comes into registry with valve 60 and differential pressure will act to continue to limit the pressure which can be built up in the groove. To secure a quantity control, a byepass valve 64, coupled to the inlet throttle valve 72, is opened. Other relief valves may be arranged in the casing wall which may lead to the atmosphere. The valves may be actuated by servomotor or other controls.

Filed: 1946-02-25
Abstract: 608,518. Variable-speed gears. MATHIS SOC. ANON. Feb. 25, 1946, No. 5869. Convention date, Dec. 22, 1941. [Class 80 (ii)] [Also in Groups XXIX and XXXIV] A supercharger impeller 7 of an aircraft engine is driven at a speed which varies automatically in accordance with the supercharger delivery-pressure acting through a conduit 46 on an aneroid 44, Fig. 3, controlling, through a fluid-pressure servomotor, a valve 32, which, by progressively throttling the common annular oil-delivery outlet 29, 30 of three gear-pumps 24, which have a common annular inlet 27 and are uniformly spaced about the impeller-axis, applies a variable brake-torque to an internallytoothed ring-gear 21 (or planet-carrier), forming the reaction-member of an epicyclic train driving the impeller, and also having external teeth 21a providing a common drive for all three gear-pumps 24. A manually- and automatically-controlled friction disc-brake 50 is also provided for the reaction ring-gear 21. The epicyclic gear shown comprises a driving planet-carrier 12, secured to the engine crankshaft 9, and carrying stepped planets, the smaller 14 of which engages the reaction ring- gear 21 whilst the larger 15 engages a driven sun 18 secured to the impeller 7. With the pump throttle-valve 32 open, no drive is transmitted and the pumps 24 circulate the oil idly from and to a reservoir. With the valve 32 fully closed, the ring-gear 21 is stationed and the impeller is driven at maximum speed. Intermediate valve positions produce intermediate speeds by allowing varying degrees of slip. To prevent undesired rotation of the reaction ring 21 duo to leakage in the fully throttled position, and also to provide a manual control for obtaining maximum speed irrespective of altitude, the reaction-ring 21 has also a manually and automatically controlled discbrake comprising an inner disc 50 on the ring, which is clamped between stationary lined discs 51, 52 when a rack 54 (not further shown) is moved axially to turn one disc 52 on a screwthread 53 on the other. Alternative gear trains comprise (Fig. 4, not shown) a simple non- stepped planet train driving through a fixed countershaft speed-multiplying train, and (Fig. 5, not shown) a stepped-planet train having driving and driven suns, the planet-carrier being the reaction member. The servomotor operating the speed-controlling throttle-valve 32, Fig. 3, comprises a piston 34, loading the valve to the closed, maximumspeed position by a spring 35, and to the open position by oil-pressure admitted from inlets 41 by a piston-valve 42, operated by the aneroid 44, on which a diaphragm-sealed screw 47 provides a datum setting. One pressure inlet 41 communicates through the valve 42 with a delivery-conduit 55 leading to the frictionbrake operating rack 54 whereby tho friction brake 50 is also automatically applied in the maximum speed position.
